Temporal structure is a key factor in determining the relatedness of multisensory stimuli. Stimuli that are close in time are more likely to be integrated into a unified perceptual representation. To investigate the age‐related developmental differences in audiovisual temporal integration and rapid temporal recalibration, we administered simultaneity judgment (SJ) tasks to a group of adolescents (11–14 years) and young adults (18–28 years). No age‐related changes were found in the width of the temporal binding window within which participants are highly likely to combine multisensory stimuli. The main distinction between adolescents and adults was audiovisual temporal recalibration. Although participants of both age groups could rapidly recalibrate based on the previous trial for speech stimuli (i.e., syllable utterances), only adults but not adolescents showed short‐term recalibration for simple and non‐speech stimuli. In both adolescents and adults, no significant correlation was found between audiovisual temporal integration ability and autistic or schizotypal traits. These findings provide new information on the developmental trajectory of basic multisensory function and may have implications for neurodevelopmental disorders (e.g., autism) with altered audiovisual temporal integration.

青少年和成人的视听时间整合和快速时间重新校准：与年龄有关的变化及其与自闭症特征的相关性。

时间结构是确定多感觉刺激的相关性的关键因素。时间上接近的刺激更有可能被整合到统一的感知表示中。为了调查视听时间整合和快速时间重新校准中与年龄相关的发育差异，我们对一组青少年（11-14岁）和年轻人（18-28岁）进行了同时判断（SJ）任务。在时间绑定窗口的宽度中未发现与年龄相关的变化，在该窗口中，参与者极有可能组合多感觉刺激。青少年和成人之间的主要区别是视听时间的重新校准。尽管两个年龄段的参与者都可以根据先前的语音刺激试验（即音节发音）迅速重新校准，仅成年人而不是青少年表现出对简单和非言语刺激的短期重新校准。在青少年和成年人中，视听时间整合能力与自闭症或精神分裂性状特征之间均未发现显着相关性。这些发现为基本的多感觉功能的发展轨迹提供了新的信息，并可能对视听时间整合改变的神经发育障碍（例如自闭症）产生影响。Autism Res 2020，13：615-626。©2019国际自闭症研究会，Wiley Periodicals，Inc.
